IMPROVEMENT IN MACHINES FOR ENTERING BLlND-SL'ATS- Specification formingpart of Letters Patent No. 139,043, dated May 20, 1873; applicationfiled October 30, 1872.

To all whom it may concern:

Be it known that I, JAMES CHURCH, of the city and county of St. Louisand State of Missouri, have invented a certain Improved Machine forEntering Blind-Slats, of which the following is a specification:

My invention consists in a frame having horizontal bars, which are sonotched as to hold the slats in the proper position to enter themortises of the stiles.

Figure 1 is a perspective view, showing one of the machines with anumber of the slats in position upon it. Fig. 2 is a longitudinalsection through one end of the machine. Fig. 3 is a perspective view,showinga modification.

A B are two similar bars, having their upper surfaces serrated, orhaving inclined planes or faces a b; the inclines of said planes beingsimilar to the inclines of the mortises c in the blind-stiles for thereception of the blind-slats. G are cross-bars connecting the bars A Btogether.

In use the machine will be secured to the work table or bench, and thestiles D and connecting cross-bar D placed outside of said machine, oneof the cross-bars D abutting against the ends of the bars A B, asindicated in Fig. 2. The slats E are then placed on the inclined planesor faces a b, the lower ends of said slats abutting against theshoulders a b of the bars A B, as indicated in Figs. 1 and 2. Theshoulders a b overhang,

so as to hold down the lower edges of the slats E. By forcing the stilestogether the slats will be guided into and readily enter the slots ormortises e in the blind-stiles.

In Fig. 3 is shown a modification of the machine, so constructed as toallow for adjustment tosuit larger or smaller sizes of sash anddifferent inclines of blind-slats. To longitudinal bars F is secured aseries of adjustable lugs, G, having inclined planes, or faces a andshoulders 11.. Said lugs G are adjusted longitudinally and inclined asdesired, and are clamped in position by set-screws g. The slottedportion of the lugs G is preferably rounded, as shown at g, to give afirm bearing on the top of the bar F at all inclinations.

The modification will be used in the same 'manner as the simple formbefore described.

A weight may be placed on the slats to keep them in position on theinclined faces a b, and against the shoulders a b.

In place of the duplicate bars A B, a single broad bar or ribbed boardmay be used; but this form would be both more cumbersome andlesseffective than the forms shown, and he obviously a mere modificationof the same.

What I claim is- The combination and arrangement of horizontal bars A Bwith inclined planes or faces a b, shoulders a b, and cross-bar G, asand for the purpose set forth.
